Abstract Copepoda constitutes a separate infraclass within Class Multicrustacea—a superclade with approximately 12,500 species. Some authorities have claimed that despite the domineering positions of insects and nematodes in the numbers sweepstakes, there are more individual copepods in the world than any other animal group.

This chapter covers the dichotomous-pictorial key for genera and species identification of planktonic Copepoda (Calanoida, Cyclopoida) reported from Europe. Here, we provide separate male and female keys to the calanoid copepods, for both, the genera and species levels.

The global diversity of free-living (non-parasitic) copepods is estimated to be around 2814 freshwater species out of around 11,500 morphospecies mostly found in marine environments (Humes 1994; Balian et al. 2008). These authors estimated the presence of 1204 species in the Palearctic area.

Diapause, Neurosecretion and Hormones in Copepoda
Nature, 1961DESPITE the great advances made during the past decade in the investigation of the endocrinology of the Crustacea Malacostraca1, little or nothing has been published on the endocrine organs or hormones of the lower Crustacea. Neurosecretory cells have been observed in barnacles2, but nothing is known for certain of any hormonal emanations from these ...

Experimental observation was carried out of four Copepoda species from the Black Sea. In the process of ontogenesis the ratio of males and females was studied as well as. the life longeivity of both. The quantitative predominance of females in the plankton can be explained by two factors - different life longevity of males and females and starting sex ...
